Ok so it's something tankies say, why is that a problem? If they said the sky was blue would you say everyone who thinks the sky is blue is a tankie?
EDIT - Just to add, you know who else reacted negatively to communists? You know why the Nazis targetted jews? Or is the irony of using "tankie" as a pejorative and being a fascist lost on you?
Why point it out? In admiration?
